I would like to present a tutorial in which I show 4 ways how to activate/start code inside your OSGi bundle. All those ways are part of OSGi 4.2 specifications. The goal of the tutorial is to explain in a short form some OSGi specifications chapters with samples. I do not like to make any deep comparison of activation ways, just overview with workable examples. All sources you can find here.

1. Requirements
2. Use Case details
3. Bundle Activator

How to replace standard Equinox shell with Apache Felix GoGo

Hello,

I've just spent some time to figure out how to integrate Apache Felix GoGo shell into Eclipse Equinox. I found two steps that should be done for this:

1. Disable standard Equinox shell and activate GoGo shell as default. Actually, it was not so complicated. One problem, that Equinox shell is a part of system bundle and you cannot just throw it away and replace with another implementation as you can do it with Knopflerfish. Equinox has runtime options to enable and disable console (-console, -noConsole). Then, to enable GoGo we have to install and start 3 GoGo bundles with runtime, shell and commands functionality. Fine! Now we can register shell commands based on GoGo API. Known issue: I could not replace shell when Equinox is started via Eclipse Launcher.
2. The second and also very important step is how to integrate Equinox shell commands into GoGo shell. I wrote some Equinox->GoGo adapter bundle that tracks Equinox shell services and registers GoGo shell service. This adapter can redirect calls from GoGo to Equinox. It can also add some usage help to Equinox commands if this help is provided by Equinox shell service. 

When above steps are finished (except support of Eclipse Launcher) we can add new shell commands with GoGo and Equinox shell APIs.

Below you can find some logs from my console and the way how you can run this on your computer.
